AUTOMATIC GASOLIN E-VEN DIN G MACHINE.

Application filed October 16, 1926. Serial No. 142.014.

This invention aims to provide a simple coin controlled mechanism for adispensing pump of the sort used in handling gasoline and other liquids.The invention aims, further, to improve generally and to enhance theutility of devices of that type to which the invention appertains. Myinvention is particularly useful in places where automobiles pass sinceone of the machines may be placed in position and'it is not necessarythat there should be an attendant in order to supply the gasoline tthose'who need it. All that is necessary,'is for the customer to deposita coin in the slot and operate the machine to get a predeterminedquantity of gasoline.

It has been my purpose'to make such a vending machine of simpleconstruction which willoperate easily, accurately and efficiently.

With the above objects and numerous others in view, the inventionresides in certain novel features of construction and in the combinationand arrangement of parts as will be hereinafter more fully described andclaimed.

In the drawing:

Figure 1 is a sectional elevation withthe cover removed of my improvedcoin control apparatus, Y

Fig. 2 is a transverse horizontal section taken therethrough,

Fig. 3 is a detail view showing one pawl and the latch associatedtherewith, I

Fig. 4 is a detail perspective viewfof one of the pawls. j v

Referring to the drawing in detailit will be seen that 5 designates thepump casing and the mechanism adapted to be disposed therein may be ofany ordinary or preferred form and operable through the verticalmovement of lift bar 6 which has rack teeth 7 on one end thereof. Acasing'8 is mounted on thecasing 5 in any suitable manner and has aremovable cover plate .9 forming one side wall thereof. The lift rackbar -6 is slidable through the casing 8 and extends thereabove. A' coinchute-f is indicated by the numeral'lO and has an exterior entranceindicated at 11 so that a coin of the proper size may be insertedtherein. -An adjustable.

stop bar 12 is mounted on the. lower portion of the bar 6 by means of 'aset screw 13 and may beset to stop the upper' movement of the lift bar 6depending upon theamount of gasoline which should be delivered in ac vrection.

' 14 there is fixed a shank 15 which extends through" an opening in oneend of the easmg and terminates in a knob 16. .-A spring 17 is disposedabout the shank l5 impinging against the casing 8 and against knob so asto hold the U-shaped member 14 normally in abutmentwith the innersurface of said one end of the casing. A coin impeding member 18 ispivoted in the casing and extends into the coin chute 10 and is normallyheld thus extended by a weighted end 19. A similar member 20is'pivotally mounted in the casing below the member 18 and to the otherside of the chute and also extends into the chute and is normally heldin such a position by a weighted end 21. In the chute between themembers 18'and 20 there is lo rated a permanent'magnet 23. An operat-1ng shaft 24 is journaled transversely in the casing and on the outerend has'an operating crank 25. A gear 26 is fixed on the shaft 2st andmeshes with the teeth of the rack bar 6. A pawl 27 ispivoted'intermediate its ends within the casing in the upper portionthereof and a pawl 28 is pivoted in the casing intermediate its ends inthe lower portion thereof. .A link 29 is pivotally e11- gaged with thepawl 27- and has a pin and slot connection with the pawl 28. A spring 30normally urges the pawl 28 to engage with the gear 26 to prevent itsrotation in a clockwise direction. A pin 31 extends laterally from thepawl 27 and a plate 32 eX- tends laterally therefrom in an opposite di-A latch lever 33 of the bell crank type is pivoted the upper portion ofthe casing and has a rod 34 pivotally' engaged therewith and extendingupwardly through an opening in the top of the case.

34 is mounted on the upper end of the rod 6 and when the rod 6 movesdownwardly it Wlll engage the rod 34 for rocking the bell An arm cranklever'or latch 33. Thislatch 33 has a notch 35 to engage the pin 31. Aspring 36'engages the catch 33 to urge it to .an engaging position atall times and also engages" the pawl 27 to urgeit to an engagingposition-with: the gear 26. The bell crank avliicli will cause therelease of has slots 38 therein for receiving screws39 so that saidscrews may be loosened and the brackets adjusted vertically so that thecatch 33 may be properly disposed.

The parts are normally disposed as shown in Figure 1 and the coin isdropped in the chute 10. This coin will engage first with the member 18and willbe retarded thereby so as to pass slowly by the magnet 23 whichwill be strong enough to hold a spurious coin. However, it the coin isgood it will rock the impeding member '20 and. stop opposite the lowerleg of the member 1a. The knob 16 is then pushed inwardly so that. thelJ-shaped memberll; through its lower leg pushes the coin against.thelowerend of a lev-er ll which is pivotally mounted in the casing andwill engage the plate 3:2 so as to rock the pawl 27 free from the gearand allow its pin 31 to be engaged in the notch 35 of the bell crankcatclr33. It

will thus be seen that the spring 30, will engage the pawl 28 with thegear 26. operator may now turn the crank in a counter-clockwisedirection until the rack bar 6 moves downwardly so as to bring the arm34 in engagement with the rod 34 the latch 83 and allow the spring 36 toforce the pawl 27 again into engagement with the gear 26 and thus thelink 29 will treethe pawl 28 from its engagement with the gear 26. Thisis so because the spring 36 works through a greater leverage than thespring 30. The pin and slot connection betweenthe link 29 and the pawl28 allows the necessary ratcheting.movement of the pawls '27 and 28.Theoperator may now rotate the gear 26 in a clockwisedirectiontorlitting the rack bar and causing the gasoline to flow out in theusual well known manner. It the coin is spurious and is stopped by themagnet QSit will be seen that when the knob 16 is pushed inwardly thed-shaped member 14% through its upper will push the coin from the magnet23 out of the chute so that it will be unable to operate in a propermanner asindicated above.

It is thought that the construction, operation, utility and advantagesof this invention will now be clearly understood by those skilled inthis art without a more detailed description thereof. The presentembodiment of the invention has been disclosed in detail merely by wayof example since in actual practice itattains the features of advantageenumerated as desirable inthe statement ot the invention and the abovedes'ciip- 's'e'cfond pawl into engagement with the gear,

tion. It willbe apparent that changes in the details of construction andin the, combination and arrangement of parts maybe resorted to withoutdeparting from-the v or scope of the invention as, hereinafter claimedor sacrificing any of its advantages.
